The TPS54495EVM-057 from Texas Instruments is an evaluation module for off-line (DC/DC & AC/DC) switch mode power supply used in applications where a regulated voltage is needed. The board uses the TPS54495 controller IC to provide a maximum power output of 35W. It features a wide input voltage range, robust design, and a high level of system integration. The evaluation module facilitates quick and easy evaluation of the TPS54495, as well as providing the user with a variety of application reference design.

The TPS54495EVM-057 can be used in a variety of applications where industry standard regulations are required for powering different components. This includes applications like digital power supplies, motor drives controllers, lighting applications, automotive, communication systems, HVAC systems, and other industrial and consumer applications. The TPS54495EVM-057 is designed to meet all safety, electromagnetic compatibility (EMC), and energy efficiency requirements for IEC 60950-1, Level B. Furthermore, the TPS54495EVM-057 is designed to meet Class-B conducted and radiated EMI guidelines.

The TPS54495EVM-057 works on the principle of pulse-width modulation (PWM). PWM is a technique used to control the output of the controller IC. It works by cycling a high-pulse width and low-pulse width at a certain frequency. The high-pulse width, or duty cycle, is the amount of time during the cycle that the output voltage is high. The low-pulse width is the amount of time during the cycle that the output voltage is low. The ratio between the high-pulse width and the low-pulse width determines the output voltage.

The TPS54495EVM-057 has several features that make it well suited for a wide range of applications. It features current mode control, feedback voltage regulation, over-voltage protection, over-current protection, and an integrated power-good signal. The current mode control enables fast dynamic response to load changes, while the integrated PWM and soft-start circuitry ensure a smooth start-up. The feedback voltage regulation provides the user with a regulated output. The over-voltage and over-current protection further improve the safety of the design by providing protection against faults and overloads.

The integrated power-good signal is an important feature that provides a digital indicator of output regulation. It is used to inform the user when the voltage is out of regulation, or has a fault. The TPS54495EVM-057 also includes a built-in dual-output voltage configuration. This feature allows the from output 28V-36V to be configured into several different dual voltages, depending on the application needs. This creates a versatile module that can be used for a wide range of applications in different industries.

In conclusion, the TPS54495EVM-057 is an evaluation module designed for off-line (DC/DC & AC/DC) switch mode power supplies. It is capable of providing a maximum power output of 35W and features a wide input voltage range, robust design, and a high level of system integration. The board facilitates quick and easy evaluation of the TPS54495, as well as providing the user with a variety of application reference design. Moreover, it is designed to meet all safety, electromagnetic compatibility (EMC) and energy efficiency requirements for IEC 60950-1, Level B.
